VEHICLE-BRAKE.

Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed March 8, 1906. Serial No. 304,972-

To all whom it may concern:

Be it known that I, JESSE H. FARMAN, a citizen of the United States, residing at 3016 North Twentieth street, Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Vehicle-Brakes, of which the following is a specification.

My invention relates to improvement in vehicle-brakes, and more particularly brakes for draft-wagons.

' other parts of the vehicle, particularly the wagon-hounds, convenient for use in connection with the invention. The driver must remain upon the loadedvehicle when going down an incline in order to operate the wagonbrake now in general use, as is well known, and where the load is bulkyas, for instance, 1 when the vehicle is loaded with hay-thei brake is practically inoperative.

tion of the present brake is certain and eifective to answer all the requirements of a vehicle-brake and is comparatively inexpensive, since the parts are few.

The novel construction and arran ement ofthe parts of the invention are fdl scribed herein and ointed out in the claims and illustrated by t e drawings, wherein Figure 1 represents a plan view of the front part of avehicle, disclosing the invention, the the brake-shoes being in contact with the wheels. Fig. 2' is a somewhat similar view to Fig. 1, showing position of the parts when the brake-shoes are out of contact with the wheels. Fig. 3 represents a vertical horizon tal elevation of a wagon-axle and rocker or bolster mounted thereon, being a rear view to more clearly show the mounting of certain parts of the invention. Fig. 4 represents a vertical side view of a ortion of front hounds to exhibit a slot to be described herein. Fig. 5 represents a Ian view of a portion of the tongue to'clear y show formation of trunnion and other parts. Figs. 6 and 7 represent side views of a art of the invention to show inclination o tongue and positions of trunnion within slot, also difierent positions of the cam; and Fig. 8 is intended to more clearly show The opera- 1 location of aperture 16 within the walls of arms 7.

i In the drawings the numeral 1 represents awagon-axle, and mounted thereon are the front wheels 2 of a wagon. The rocker orbolster 3 is mounted upon the axle 1 and held in position by the coupling-pin 4, the latter passmg through the reach 5. Therear hounds to the front gear are shown by the numeral 6. The parts thus mentioned are common to all wagons, and for the purposes of my invention I construct a a1r of slidable arms or links 7 and mount t em one upon either side of the tongue 8 in a manner presently described.

I construct front hounds 10, which ass rearwardly through apertures 1 1 of the ax e 1, the ends being extended to a point between and. somewhat to the rear of wheels 2 to furnish the pivotal mounting 12 of the brake levers 13. The tongue 8 is provided with the trunnion 9, seated in slot 14 of the heads 15 of hounds 10. The arms 7 are provided with suitable apertures 16, Fig. 8, to furnish a mounting upon trunnion 9 and ass rear wardly substantially parallel with t he tongue through apertures 18 of axle 1 to points between the rear partsof wheels 2 where they are pivotally mounted at 17 upon the inner ends of brake-levers 1 3, and upon brake-levers 13 I rigidly mount brake-shoes 19.

The backing movement of a vehicle is performed by the team, the neck-yoke forcin the tongue backward, asv is well known, an from the description given it will be readily understood that the tongue 8 is slidable lengthwise between heads 15 of the hounds a limited distance, this distance being the extent of slot 14, and when slot 14 is 0 en or unobstructed a backing movement 0 the team will cause trunnion 9 to travel backward the length of slot 14, as is evident, carr ing with it the arms 7 mounted thereon, at w ich time the parts will be in the position shown by Fig. 1. At the time of this movement the inner faces 19 of heads 15 furnish a bearingsurface for the sliding thereon of arms 7, and the tongue being positioned between these arms the heads 15 operate in a manner to the brakes operate in a very effective manner, since the greater lnchne causes a correspondingly-greater impact of the brakes upon the tires and requires no attention of the driver whatever. The employment of the invention is of great utility when drivin a restless or fractious team, as the ordinary hand-lever brake is an incumbrance, and for use of farmers when moving bulky loads the invention is very useful.

When backing the vehicle on level ground, in order to prevent a contact of the rake with the tire a backward movement of the tongue is prevented by any convenient means, as by obstructing the slot 14 by means of the cam 21, adapted to swing within and occupy a rear portion of slot 14 when desired.

The parts are few and not expensive in construction. The pivotal mounting at 12 of levers 13 may be varied in the distance between the brake-shoes and the mountin at 17 by constructing the hounds 10 at a di 'erent angle, and the slots 22 may be used to permit a true lengthwise movement of the arms 7 while causing a partial rotation of the brakelevers. The parallel heads 15 of the hounds 10 are maintained in a fixed relative position in any convenient manner, as by the crosspiece 24, the arms 7 being housed within slots 23.

What I claim as my invention is 1. In combination with a wagon axle, wagon-hounds, and the front wheels of a wagon; a vehicle-brake comprising a trunnion formed upon said wagon-tongue; arms mounted upon said trunnion and extending rearwardly through said wagon-axle to adjacent points between said wagon-wheels; said wagon-hounds formed with parallel portions, and angularly extending portions; a slot formed within said parallel portions of said wagon-hounds; said wagon-tongue and said arms mounted between said parallel portions of said wagon-hounds; said trunnion of said wagon-tongue seated in said lengthwise slot of said parallel portions of said wagon-hounds; each angularlyextending portion of said WEL OIl-llOUlIClS passing rearwardly through said wagon-axle and positioned between one of said wagon-wheels and one of said arms; a brake-lever pivotally mounted upon each of said arms and each of said angularly-extending portion of said wagon-hounds; and means to cause a partial closure of said lengthwiseextending slot formed within the parallel portions of said wago'n-hoiuids.

2. A vehicle-brake of the class described in combination with a 'WZLgOlT-iLXlG, a wa ontongue, the front hounds and front wheels of a wagon; the trunnion 9 formed upon the.

tongue; the arms 7; the a ertures 18 formed within said wagon-axle tli pivotally mounted at 12 and at 17; the slot 14 adapted to receive the trunnion 9; the slots 23 formed between said tongue and said hounds and a means to cause a partial closure of said slot 14, substantially as set forth and described.

In testimony whereof I have aflixcd my signature in presence of two witnesses.
